It's been a while since we were teased about a radical P1 and McLaren delivered, it's their track-ready P1 GTR. So let's start with the numbers, power output of 1000HP, which is from the both electrical and combustion engines. Turning it into a track-toy, has widened the front track by 80mm and the car sits lower by 50mm. McLaren states that they reduced the overall weight by 50kg, due to motorsport solutions.

Side windows are made of racing polycarbonate, the glass roof has been replaced by carbon fiber, the same treatment happened to the engine cover.

"Best driver's car in the world on track", anyone? At least this is what McLaren aims to do with this model. Unveiled as a concept study at Pebble Beach this weekend, the GTR features a tweaked V8 3.8-liter twin-turbo mid-mounted engine and the electric motor and managed to bump output of the hybrid system from 916 PS (674 kW) to 1,000 PS (736 kW).

The car has also been aerodynamic adjusted, with a fixed ride height, front splitter and carbon canards, redesigned skirts and carbon spoiler - with hydraulic DRS.

The Nissan GT-R or as many call it, "The Supercar Slayer," is back at it again to test its jaw-dropping performance. Last year, in November, the GT-R went around the Nurburgring in just 7:08.679 and it was labeled as the fastest production car to date. However, the car they used was pre-tuned with a package called the "N-Attack." This time, Nissan has decided to release a video of the GT-R Nismo with the N-Attack package installed, running a lap around the Fuji Speedway in Japan.
